N0. 98, also known as RELIEF, HANDKERCHIEF SHOAL and other names, was a lightship that functioned as a lighthouse in areas where lighthouse construction was not suitable. Built in 1914, the vessel served at Buffalo on Lake Erie and at Lansing Shoals in northern Lake Michigan. It was retired at age 40 in 1955.

Three miles off Milwaukee in the early 1930s was a speck of blinking light that few people knew came from a lightship called MILWAUKEE. The ship’s crow’s nest on top of the mast encircled the lantern that created the light to warn vessels of their proximity to Milwaukee’s harbor. She was decommissioned in 1965.

The North Point Lighthouse in Milwaukee overlooking Lake Michigan is on the National Register of Historic places. It is located in Lake Park which was designed by Frederick Law Olmstead in 1893.
